During construction and supervision of electrical equipment calculation Notes

Should be selected Substation Design capacity when entering the primary current, CT, Wave-type, non-current-limiting fuses, MOF specification, ASS settings, transformers, capacitor capacity, secondary current, secondary breaker capacity, the two kinds of ground wire thickness .

Load capacity condenser, asking for the current power factor, input power factor when the target capacitance required, jeolgamyul current, power loss reduction, it is possible to obtain an equivalent dose, single-phase capacitor and three phase capacitor value of the reactive power.

Depending on the construction method allowed when the wire current-wire method selection circuits can be selected wire size in advance. Construction methods note attached.

The tray area can be calculated according to the wire size.

KEPCO know the facility charges (processing, underground, added distance), and it can be seen that the use of pre-construction safety inspection, periodic inspection, electrical safety check amount.
